Abstract

The greenhouse (6) is made from curved plastic tubes, on which nozzles (9) are mounted. Water is fed through these by a pump (2) which is operated by solar power generated by a panel (1) connected to a storage battery (4), giving controlled irrigation.

Description

<Desc / Clms Page number 1>

The present invention relates to an automatic watering device by a structure of plastic tubes fitted with sprinklers and supplied with water by a lifting pump itself supplied with energy by a solar panel.

Traditionally, these greenhouses are made of metal and require manual watering or a watering device independent of the metal structure and a water point near the plantation.

The device according to the invention requires a water point which can be lower than the level of the plantation, a lifting pump which feeds a tubing of plastic materials, an electrical cabinet containing the automation system and an accumulator, and a solar panel supplying this electrical cabinet.

 This first module (Fig 1) can be connected with one or more other similar installations located at a distance or at higher levels.

From the second level, the installations must be coupled with a sealed storage tank (Fig 2) allowing each greenhouse to have a minimum of water ensuring a watering cycle. The tanks of the annexed structures will then be supplied with water through a 3-way solenoid valve when the watering cycle on the lower level is completed. Each pump is then supplied by its own solar panel, regulated by its own automation cabinet and can thus benefit from a different watering time depending on the greenhouses.

électrique classique. Dans la mesure où l'ensoleillement est suffisant, ce dispositif ne demande aucune intervention humaine excepté la maintenance normale et les travaux de semis et récolte. This device allows the irrigation and watering of agricultural land not exploited from a water point and without requiring any supply

classic electric. Insofar as there is sufficient sunshine, this device requires no human intervention except normal maintenance and sowing and harvesting work.

The accompanying drawings illustrate the invention: Fig 1: Basic module-diagram Fig 2: Upper module with tank-diagram Fig 3: Tee with nozzle-sectional view Fig 4: Plate clamp-diagram On the schematic diagrams (Fig 1 and Fig 2 ) we have a solar panel (1), a pump (2), an automated electrical cabinet (3), an energy accumulator (4), a solenoid valve (5), a plastic tubular structure (6), a storage tank storage (7), a level (8) and sprinklers (9).

 According to a variant not illustrated, an intermediate module can be installed without a sprinkler structure (6), this module would then comprise a reservoir (7) and would allow a lifting of the fluids to a higher level.

 According to another variant not illustrated, the plastic tubular structures (6) can be joined and rigidified by the addition of plastic tensioners or threaded rods. Platinum collars are then used (Fig 4) clipped onto the tubing of the sprinkler structure allowing precise adjustment and increased rigidity of the structure.

According to another variant not illustrated, the entire sprinkler structure (6) can be protected from animal intrusions by the use of a mesh in the lower part and an anti-volatile net in its upper part.

Claims (4)

1-This device intended for carrying out agricultural plantations on land raised above a natural water point is characterized by the use of the energy accumulated by a solar panel (1) to be stored in an accumulator (4) incorporated in an automated cabinet (3) and which will trigger the lift pump (2) thus supplying a structure in plastic tubes (6) equipped with nozzles (9) to thereby trigger a timed sprinkling (Fig. 1).  2-The device according to claim 1 characterized in that the structure in plastic tubes (6) is protected from animal intrusion by a rigid mesh in its lower part, around its entire periphery.  3-The device according to claims 1 and 2 characterized in that the plastic structure (6) is protected in its upper part by an anti-volatile net and thus replace if necessary the protective mesh against animal intrusions in the lower part.  4-The device according to any one of the preceding claims, characterized in that clips are fitted to the plastic tubing of the sprinkler structure (6), collars fitted with a plate with 3 holes making it possible to stiffen the assembly of the watering structure by the use of tensioners or threaded rods (Fig. 4).
